SPECIFICATION forming part of- Letters Patent No. 769,055, dated August30, 1904. Application filed November 17, 1903. Serial No. 181,510. (Nomodel.)

To all whom, it may concern:

Be it known that I, GEORGE LINCOLN B M- GARDNER, a citizen of the UnitedStates, residing at Gridley, in the county of Coffey and State ofKansas, have invented certain new and useful Improvements inCultivator-Shovels; and I do hereby declare the followingto be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to cultivator shovels or teeth, and has for itsobjects the economical production of. a cultivator shovel or tooth whichis of light draft, on which weeds and trash do not collect, one which iscapable of form of embodiment of my invention, in whichdrawings likereference-symbols indicate corresponding parts, and in which Figure 1 isa front elevation of a pair of cultivator teeth or shovels of myinvention shown on either side of a plant. Fig. 2 isa sectional view onthe linew m of Fig. 1. Fig. 3 is a sectional View on the line y 1/ ofFig. 1, and Fig. 4 is a perspective view of my device.

Referring to the drawings, a is the moldboard, having its upper sidesinclined back from the'central vertical line a (shown in a dotted line,Fig. 1,) and b openings therein through which bolts or other meanssuitable to attach same to a shank may be passed. The straight edgethereof, (6 terminates in the point a, and is adapted to stir the soilnear the roots of the plant cultivated. The share thereof, 0Z, isformedintoia cutting edge (Z on an angle to said straight edge. 'Said share iscurved or inclined upward and backward from the cutting edge, which inoperative position is nearly horizontal. '7

When the device is moved forward, the edge 0Z cuts into soil, and theupwardly-inclined or curved plane of the share carries the weeds openinge, formed between the share and moldboard, thus preventing clogging andleaving the soil turned over and smooth behind it.

In the, operation of the device it is obvious that the cutting edge d ofthe share will be nearly horizontal and cut the weeds to a distance atone side of the plant cultivated, while the narrow moldboard a affordsno point of attachment for weeds and trash, and yet affords a very lightdraft and throws sufficient soil to the plant. The inclined planes ofthe moldboard and share throw the soil and weeds through the opening 0and leaves the soil turned smooth and also leaves a very shallow furrow.It will also be obvious that the straight edge a of the device allowsoperation very close to the plant without danger of breaking it down,throwing enough soil to it to cultivate the plant properly, and thiswithout the use of fenders or other like'devices.

The shovel or tooth of my construction may be stamped out, forged, orformed in any suitable manner; but its peculiar shape allows it to bestamped from a straight strip of metal without waste, as by. turning thetops of two points together a parallelogram is formed. It may be used ingangs to cultivate a wide space, or two shovels only'may be used, or theshovels may be shifted to throw the soil either to or from a plant, asmay be required. Many'modifications of my invention may be made Withoutdeparting from the spirit thereof. Therefore I do not desire to belimited to the exact form herein described and illustrated.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is
